CapCut Timeline Preview Bar Not Working on Android

Many Android users of CapCut face a frustrating issue where the timeline preview bar — the bar that lets you scrub through your video while editing — stops responding or freezes. This makes precise editing difficult and slows down video creation. Fortunately, there are several practical ways to fix it.

Why the Timeline Preview Bar Stops Working

1. App glitches or bugs
   • Temporary errors in the app can cause the preview bar to freeze or not respond.
2. Device memory or performance limitations
   • Editing long or complex videos consumes RAM and CPU. Older or low-end devices may struggle, causing the preview bar to lag or freeze.
3. Corrupted cache or project files
   • Stored temporary data can interfere with CapCut’s timeline functionality.
4. Outdated CapCut version
   • Older versions may have bugs that prevent smooth timeline scrubbing.
5. OS compatibility issues
   • Certain Android versions may have minor conflicts with CapCut’s timeline functions.

3. Free Up Memory and Storage

7. Test on a Different Device (Optional)

• If possible, try opening your project on another Android device.
• If the timeline works there, your original device may not meet performance requirements for the project size.

8. Avoid Overloading Timeline

• Limit the number of heavy effects, AI tools, or long clips in one project.
• Use CapCut’s split and merge strategy: edit smaller segments separately and combine them later.

Tips for Preventing Timeline Problems

• Keep your CapCut app updated regularly.
• Avoid opening too many apps in the background while editing.
